Garbage-collect the old Shark-specific "pccons" stuff. Shark has
been wscons for some time now.

"ofisa" carried an "ofbus" interface attribute in addition to its own
in order to attach an "ofrtc" instance. This worked prior to the
autconfiguration system enforcing non-ambiguous interface attribute
specificaitons due to how the attach args for ofisa were structured.

But it no longer works, and is a big dodgy barring a formalized "subclassing"
facility for interface atributes in config(5).

So, stop using "ofrtc" on Shark, and replace it with an ofisa driver for
the mc146818 real time clock hardware, and remove "ofbus" from "ofisa".

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything

many redundant options.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options

The rnd pseudo-device is not really optional, because it is in the same

This fixes build breaks on several ports. Thanks to Havard Eidnes for

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

Remove the portalfs kernel file system driver. Replace mount_portal(8)

Remove SHMMAXPGS from all kernel configs. Dynamically compute the
initial limit as 1/4 of the physical memory. Ensure the limit is at
least 1024 pages, the old default on most platforms.

Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

Drop pccons. Obsoleted by wscons, now fully supported in NetBSD/shark.
OK'ed by thorpej@ and tsutsui@ a while ago.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Switch NetBSD/shark's installation kernel and disk image to use wscons

This obsoletes pccons in this platform, which will probably be removed

- Document COMPAT_15 as doing nothing
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.

they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

...and bump the ramdisk size to 3.5M (ELF binaries are somewhat
larger on-disk due to the way the linker pads out the .data program
